`__private_extern__` being used.

Some information about this can be found
[https://developer.apple.com/library/mac/#documentation/developertools/Conceptual/CppRuntimeEnv/Articles/SymbolVisibility.html
on Apple's website]. I think it's a darwin specific feature, but I
couldn't find confirmation of that. A quick check shows they only appear
within one of the `ifdef`'s below
{{{
#elif defined(VGP_x86_darwin)
#elif defined(VGP_amd64_darwin)
#elif defined(VGO_darwin)
}}}
other branches seem to just use `extern`, but I readily admit to not
taking the time to figure out what difference it would make.
